Be careful with this company - their billing practices are completely bogus. Our 2 boys came to the Little Gym for 3 months. They liked it at first, but then they got bored. So after 50 days, we gave them 30 day notice and were surprised when our credit card was charged again.
It turns out that your "last month's" payment doesn't actually cover anything and they will charge you anyhow. I spoke with the owner about it. She was rude and told me that we were given too big of a discount to start, which apparently justifies her trying to screw us at the end. She made up a ridiculous story about how we begged for a discount (her employees OFFERED US the twin discount).
The owner thinks it is fair that we paid for 4 months of service, when we only used it for 3 months (and gave our 30 day notice well in advance before the 2nd month had ended). We were also charged a random "membership fee" about a month into our experience (we were not told about this at signup). Now I am left to fight this through my credit card company.
My opinion - kids like this place the first few times, but it is WAY too expensive and their shady business practices make it impossible for me to recommend this place to anyone.
